The Leptospira spp Real-Time PCR assay can detect Leptospira species in blood during the acute phase of the infection, usually during the first week prior to seroconversion. Detection in urine is usually 7-14 days post infection, and it may or may not be detected in the blood at this time. We recommend testing both blood and urine due to variations in shedding. * Fee is $32.50 each for the first 2 tests, each additional test at the same time is $22.50 per test. Discount applies to samples submitted at the same time - same owner - per accession.
